IMPROVEMENT IN FLUTlNG-MACHINES.

Specification forming part of Letters Patent No. 188,568, dated March 20, 1577; application tiled December 9, 1876.

To all whom it may concern:

Be it known that I, JAMES EDWARD WIL- SON, of Bridgeport, Fairfield county, and State of Connecticut, assignor to JAMES WILSON, of said Bridgeport, have invented a new and useful Improvement in Fluting-Machines and I hereby declare that the followingis a full, clear, and exact description thereof, reference being bad to the accompanying drawings, making a partof this specification, and to the'letters of reference marked thereon, in which the same letter represents the same thing in each figure.

Figure 1 is a side elevation of myimproved fluting machine; Fig. 2, a rear elevation thereof.

My improvement relates to the arrangement of the devices permitting the insertion of the material to be fluted.

Heretofore, the upper fluting-roll has been held to the lower roll by a tension-spring, which did not permit of the elevation'of the upper fluting-roll to insert the material be tween the rolls, without relieving the pressure of the tension-spring, whereby considerable time and strength were expended, and constant readjustment made necessary, to prevent variable tension.

I raise the upper fluting-roll independently of the tension sprin g, so that when the proper What I claim, and desire to secure by Letters Patent, is

The com bination of upper tinting-roll I, bowspring A, thumb-screw H, and lever-arm C,

constructed and arranged substantially! as and for the purposes described.
